From an article in Tech and Learning:


After reading many articles and comments from teachers, I notice a common question is "Are there any good apps for free?" The answer is yes! In addition, many apps offer a "lite" version to try before purchasing. Many of the lite versions just have advertisements so it's well worth installing, if it is a good app.

AppsGonefree - good app to find free stuff!
